description Largetooth Sawfish Overview
The largetooth sawfish (*Pristis pristis*) is a critically endangered species of ray belonging to the family Pristidae, found historically in tropical and subtropical coastal waters globally. It is characterized by its long, flattened snout lined with lateral teeth, which it uses to slash at schools of fish and probe for crustaceans in the substrate. As an euryhaline species, it readily enters freshwater river systems, lakes, and estuaries. Populations have severely declined due to overfishing, habitat destruction, and bycatch.

Largetooth Sawfish ranks #7 of 160 in the Ray ranking, behind Giant Freshwater Stingray, ahead of Bluespotted Ribbontail Ray.
help Largetooth Sawfish FAQ
What is the defining physical characteristic of the Largetooth sawfish?
The Largetooth sawfish (*Pristis pristis*) is famous for its long, flattened rostrum (snout) that is lined with lateral teeth. This saw-like appendage is used to slash through schools of fish and to dig in the sediment for crustaceans.
Is the Largetooth sawfish a shark or a ray?
Despite their shark-like appearance, sawfish are actually a type of batoid ray. They belong to the family Pristidae and have gill slits located on the underside of their bodies, which is a key trait of rays.
Where do Largetooth sawfish live?
Historically, they were found in tropical and subtropical coastal waters, as well as freshwater river systems, all over the world. Today, their populations are heavily fragmented, though they can still be found in places like the Amazon basin and northern Australia.
Why is the Largetooth sawfish critically endangered?
Their saw-like snouts easily become tangled in commercial fishing nets, leading to high bycatch mortality. Additionally, their coastal river nursery habitats are heavily degraded by human development and pollution.
